WebIn conclusion, we were able to learn how to get accurate measurements and use the micrometer, vernier caliper, height gauge, etc. A measurement is the process of obtaining the magnitude of a quantity relative to an agreed standard. The Purpose of this lab is to introduce the basic measurement techniques for the fundamental quantities such as length and mass, to introduce quantitative analysis tools such as the average and the percent difference, and to reinforce other concepts such as unit conversion. Repeat this procedure in liquid (brine) and record the immersed length. It will increase the Sigma level, The project Champion/Sponsor has asked for condensed project updates throughout the life of the project. Description of Apparatus.

To calculate the least count of the vernier scale, i.e., how much one division on the vernier scale values for, proceed as follow: So, the least measurement one can take with the combination of these two scales is the difference between them. easily pivot about the fastener points. The vernier calipers work on the basic principle of alignment of measurement markings on the vernier scale and main scale. Lee, Ke-Yu et al.
